COMBINED SYSTEM OFREGENERATIVE HEATING AND VENTILATION.

To all whom it may concern:

Be it known that I, STACEY FISHER, a citizen of the United States,residing at 2384 East Sixty-seventh street, Cleveland, in the county ofCuyahoga and State of Ohio, have invented a new and useful CombinedSystem of Regenerative Heating and Ventila- Speciflcation of LettersPatent.

tion, of which the following is a specifica-' tion.

My invention relates to an improved system of regeneratlve heating andventilation,

, the primary object being to provide a generally improved system ofheating and forced ventilation for use in connection with dwellings,houses, apartments, and the like.

A further object is to so arrange and dispose the fresh air conduits andinlet ports relative to the foul air conduits and ports and the heatingunit and fines for the escape of the products of combustion as to resultin an improved system of heating and ventilation.

In carrying out my invention for' the purposes above mentioned I preferto provide a main flue or air chamber extending through theroomstobehea'ted and surrounding the furnace flue for the escape of theproducts of combustion, said main flue or air chamber being provided atsuitable intervals with ports intersecting the lower portions of therooms to be heated and ventilated and being also provided with aplurality of vertically disposed fresh air inlet pipes surrounding thefurnace flue and communicating at their bottom with a suitablesuction-fan or blower adapted to draw the fresh air through the inletpipes from a main fresh air conduit and to discharge the same over theheatingunit and through the hot air pipes or conduits leading to therooms to be heated.

By the above arrangement a large part of the heat from the foul air andthe flue gas escaping upwardly through the main flue or air chamber isutilized in gradually warm-- ing the fresh incoming air drawn downwardthrough the vertically arranged inlet pipes surrounding the furnace fineor pipe and arranged within the main flue or air chamber. 'By myimproved system, the follow- I ing results are obtained: (1) a more samtary system of ventilation than the ordinary methods commonly employed;(2) a more economical system of heating through the general arrangementand combination of the parts and the forced ventilation and distri-Patented Apr. 22,1 913.

bution of heated air; and (3) a more perfect system of air distributionand ventilation.

With the above mentioned and other ends in "view, the invention consistsin the novel construction, arrangement and combination of parts hereindescribed, illustrated in the accompanying drawings, and particularlypointed out in the appended claims Referring to the drawings forming apart of this specification, Figure 1, is a vertical central sectional.view of a house equipped with necessary apparatus for carrying out myimproved system of heating and ventilation. Fig. 2, a horizontalsectional view taken on line M-N of Fig. 1.

In carrying out my invention, I provide a main fine or chamber adaptedto extend from the basement through the roonis to in: heated and toconduct the foul air from the latter through themedium of the foul airinlet ports or openings 11, I, S, and Q. the latter being preferably inthe lower portions or near the floor lines of the rooms to be heated, asshown.

The heater H, may be of any suitable and convenient form or type, and asshown in the present instance, maybe provided with heating coils C, forhot water or steam, said coils being adapted to form the heating unitand inclosed within a casing as shown, and the furnace flue leading fromthe heater H, is arranged centrally of the main flue or air chamber.

The fresh air supply comprises a fresh air conduit '1, preferablyarranged in the upper portion of the building as shown, said fresh airconduit intersecting the main flue and terminating in a drum or manifold1), surrounding the upper portion of the furnace flue and communicatingwith a plurality of vertically arranged air inlet pipes arranged aboutthe furnace flue and preferably in close proximity to the latter, saidvertically arranged fresh air inlet pipes terminating at their lower endina second or lower drum manifold D, the fresh air being drawndownwardly through the fresh airinlet pipes by means of a suction fanRand forced from the latter through the medium of :1V pipe P, leadinginto the lower portion of the casing surrounding the heating coils C. Asthe air passes over the coils C, it is heated to the requisitetemperature and is forced upwardly through the hot air pipe or flue J,the latter being intersected by suitable registers intersecting therooms to be heated through the side walls thereof, and preferably nearthe upper portions of said rooms, and the hot air thus forced into therooms set S to displace and force out the foul air in the lower portionsthereof and out through the openings It, 1 S, and Q, as indicated by thearrows. The heated foul air passing out through 'said ports comes int-ocontact with the fresh air inlet pipes connecting the drums or manifoldsD, and acts to initially warm the incoming fresh air passing downwardlythrough the fresh air plpes to the suc-' tion fan, the heated foulairpassing upwardly through the main flue and out through the openingsG, of the latter, as shown.

rom the foregoing description, taken in connection with the accompanyingdrawings, the operation and advantages of my invention will be readilyunderstood.

Having thus described one of the embodiments of my invention, what Iclaim and desire to secure by Letters Patent is,

1. In a heater and ventilator, a main flue extending through the roomsto be heated and provided with foul air inlet ports leading from thelatter, a furnace flue mounted therein, a heating unit, a casingsurrounding the latter, a plurality of fresh air inlet pipes surroundingsaid furnace flue and terminating in upper and lower manifolds, a freshair inlet conduit leading to said upper manifold, and a suction fan andconduit communicating with said lower manifold and casing, said casingbeing provided with a hot air conduit leading to the upper portions ofthe rooms to be heated.

2. A heater and ventilator, comprising a main flue extending through therooms to be heated, and provided with foul air ports communicating withthe latter, a furnace flue therein, a plurality of vertically arrangedfresh air inlet pipes terminating in manifolds surrounding said furnace.flue, a fresh air conduit leading to one of said manifolds, a suctionfan communicating ,with the other manifold, a heating unit adapted toheat further the incoming air as received from said suction fan, and ahot air conduitleading from said heater to the upper por tions of therooms to be heated.

3. A heating and ventilating system, comprising a main flue extendingthrough the rooms to be heated provided with foul air inlet ports in thelower portion of the latter a heater, a furnace flue arranged within'saimain flue, a plurality of vertically arranged fresh air inlet pipesarranged-about said furnace flue and within said main fiue, upper andlower manifolds communicating with'said verticallyarranged freshair-inlet pipes, a fresh air conduit leading to said uppermanifold, asuction fan communicating with said lower manifold and adapted todischarge the air to said heater, and a hot air conduit leading fromsaid heater and communicating with the rooms to be heated.

4. A heater and ventilator, comprising a main flue extending through therooms to be heated and provided with foul air ports communicating withthe latter, a furnace flue in said main flue, fresh 'air inlet pipesspaced about and surrounding said furnace flue and terminating at theirends in manifolds, a fresh air conduit leading to one of said manifolds,a suction fan communicating with the other manifold, a heating unit, acasing surrounding said heating unit, a pipe leading from said suctionfan to said casing, and a hot air conduit leadinggfrom said c'asing tothe rooms to be heated.

5. A heating and ventilating system, comprising a main flue extendingthrough the rooms, to be heated and provided with foul air inlet portsin the lower portions of the lat-,

ter, a heater, a furnace flue arranged within said main flue, a seriesof freshair inlet pipes arranged about said furnace flue, upper andlowermanifolds surrounding said furnace flue and communicating with saidpipes, a fresh air conduit leading to said upper manifold, a suction fancommunicating with said lower manifold and said heater, and a hot airconduitleading from the latter to the upper portions of the rooms to beheated.
